Windforce 290 Crossfire

[Skurge]

So I finally got my cards today, although I feel like Gigabyte Sent me a 290X in a 290 box by accident. I don't know if this is a bug with GPU-Z of if I did get a 290X

First card

Second card

Anyway I can quickly verify this. It's late and I don't want to remove each card and benchmark them.

Something seems a little off on the second card. Look at the bandwidth/bus width.

Other than that the shaders/ROPs/TMUs are accurate for 290x specs.

GPU-Z normally does that with the second in my experience.

What do the stickers say on the card? I think you did get a 290x by mistake.

Yes this is true.

How are the temps of 2 of these in crossfire?

The top card topped out at 89C bottom card was 78C.

I will check the stickers now.

I've had that happen on my Sapphire Tri-X 290s in Crossfire and my MSI 290s in Crossfire. May be a bug with GPU-Z or something with how Crossfire is implemented in the 290s. However, checking with HawaiiInfo verified they were all locked 290 chips.

Try disabling crossfire and see if it gives more accurate numbers?

Good temps for crossfire. That board gets ya 2 slots between xfire cards?

I didn't read as many reviews on the gigabyte 290 Windforce as I did of the MSI and Sapphire non reference 290 cards.

Interested in your initial impression once you fire up your go to games.

GDDR5 Elpida = 5000Mhz max before it artifacts. You need either Hynix or Samsung for the Memory to hit over 5000Mhz.

WinForce = 1130 to 1180 MAX before your screen Blackens with +.156mv when benched with temps for the GPU/VRM hitting 92/120C and throttling.

Under water 1230 to 1258 Mhz for the GPU with +0.136mV when benched temps GPU/VRM approx 67/78C and no throttling.

Hawaii may very but not from I've experienced. A 290X Binned Hawaii appears to clock approx 100 Mhz faster then a 290.

Would very much like to see an Enigine Valley Bench Posted in our Forum ;o)

That's a pretty accurate description, my friend has a reference card with elpida unfortunately, he gets it to 1180/1250 and anything at all over that artifacts, although the gelid icy vision must be a better cooler, because his doesn't get that hot in his not-so-great case

The AMD OEM Cooler does a good job at cooling the GPU and VRMs and will MAX Hawii Specs under AIR - say at 1170/1500 @ +0.156mV with temps of 90/95C and throttling when Benching - but it NOISY.

Great GPU's running at 1250/1500mhz+ (Pending vRam) and +0.132mV under Water ;o)

 

[Z15CAM]

+0.62mv and 1258/1500 Mhz for Benching - short durations. I run my XSPC Razor Ref GA-R9 290X Elpida at +0.143mv 1230/1500Mhz 24/7 and I mean 24/7 without issues between 38C to say 74C when Benched and VRM's are below 76C under extreme load. Really like the card under water - PERIOD.

I can play BF4 under DX on a 120Hz 2560x1440 PLS DVI-D display like Butter as an actor in a movie - Smooth ;o)

Waiting for a few more Catalyst improvements before I venture into Mantle by then I may be fast enough - LOL.

Yeah the board does. The XDMA bridgeless crossfire is perfect for that!

I love the MSI Gaming so far, the only hesitation I have now is when I think about going quadfire, then again it should probably be on the 2011 platform by that point.

So I popped the cards in individually and they are in fact 290s. GPU-Z has a bug. But after putting them back in. When I'm on the desktop. My monitor drops signal and then the audio freezes and I have to reboot the system and it does it again. Within about 20mins of booting. It didn't do it before I removed the cards. I played BF4 for a good 2hrs before. Now it doesn't last 10mins on the desktop. I tried with a single card and it works fine. I will test the other card when I get home today.

Congrats on getting the 290s. Once you get the CF figured out I'm anxious to see the performance.

Maybe flip the cards, from top to bottom?

It should not make a difference, but who knows. Multi GPU's are such babies.

Turns out I had to RMA one of the GPUs so I can only provide single GPU benchmarks.
